An overview of some of the projects we have successfully delivered to Clients can be found below:

A Global Insurance Organisation
OCS were called upon by a global insurance organisation after a large acquisition was made, OCS were tasked with the job of integrating the acquisitions Oracle estate within the clients internal platforms, OCS covered all aspects of this project, including the design of all databases, specification for the correct infrastructure setup, installing on a Linux VM with Data Guard replication. OCS carried out the data cut-over, once this was complete OCS then undertook data quality assessment to ensure any data errors could be noted and addressed. During this integration OCS upgraded from Oracle 10g to Oracle 19c and once live OCS supported the system.  In addition, OCS undertook changes to fix some outstanding performance issues and to automate some processes.

Leading NfP Organisation
OCS Consultants were tasked to analyse and develop data integration strategies as per the Client's standards for a development of Data App. Implementing a Data transformation process using ODI 12C from multiple source systems, e.g. Flat Files, SQL Server, Postgre DB and Oracle 19c database and to create a Data Warehouse. Maintain the Data dictionary and technical documentation for the developed logics in Confluence. Management of the DDL scripts and PL-SQL code versions in the Bitbucket. OCS Consultants worked closely with a BA and quality engineers to understand and estimate the tasks providing a timely solution.

A leading Media Company
OCS Consultants undertook multiple Oracle database legacy conversion from 11gR1 to 11gR2 ( Exadata as a consolidation platform exercise for a number of high end transactional billing and distribution systems.  Databases of various sizes are in the process of migration, the smallest 200gb the largest 20Tb.  In moving to a 2 compute node Oracle Exadata X3 platform (OEL V5.5), OCS was also tasked with looking at ways of improving throughput, increasing system stability and driving down storage costs.

An International Travel Company
OCS offered 3rd line support for a new Exadata 11gR2 (X2 half rack 4 compute and 7 cell node) deployment covering a variety of Oracle database types (Datawarehouse. OLTP and DS system) as a consolidation engine.  OCS initially reviewed current performance issues with the DSS loaded application, determined the root cause, having checked cell/compute node utilisation, recommended plan stability fixes using SPM and implemented these changes resulting in a tenfold reduction in batch runtimes to bring application runs in tolerance.

A large UK Investment Bank
OCS Consultants were tasked to analyse, full performance review and recommended beneficial improvements to the Banks critical business systems, for high net worth individuals and corporate clients, running on either Investment or Retail Bank Oracle database infrastructures.  To assist 1st line production support DBAs in performance and stability problem diagnosis and resolution of production issues on a number of systems under review, supported production rollout of code, tuned pre-release code/test harnesses and performance engineered production solutions fit for production running and migration strategies from legacy Oracle solutions to Linux/Oracle RAC cloud based infrastructure.  This has been across platform and operating versions including AIX, Solaris and Linux (Red Hat 6) covering Oracle 10gR2/1, 11gR2/1 and Oracle 12c.

A Multi-national Software House
OCS Consultants were involved in assisting with a 22,000 concurrent user performance test covering the whole business lifecycle for online day peak hour processing, batch overnight activities, Oracle Apex front end development, Oracle Streams replication and data migration utilities.  Also responsible for upgrade of the database architecture from Oracle RAC 10gR2 to 11gR2 (1 terabyte database) performance engineering regression testing and evaluation of new 11g performance features under full peak load.

A European Telecoms Regulator
OCS Consultants were asked to design, engineer and build Oracle 64 bit 11gR2 Linux RedHat 5.5 RAC clusters to support the clients Spectrum Analysis application with full disaster recovery infrastructure using Oracle Dataguard for both pre-production (UAT) and production services.  The current production system (MS Windows Server 2003) was underperforming and experiencing serious performance degradation when under load.  Implementing Red Hat 5.5 Linux the solution improved the business with significantly enhanced systems stability and reliability.  This deployment was delivered ahead of schedule and on budget.

UK Internet Gaming Company
OCS were asked to undertake full performance engineering analysis on the core trading system supporting 10,000 concurrent sessions across two RAC Linux Red Hat 5.4 clusters running Oracle 11gR2 CRS and 11gR2 RDBMS on a 1.3 terabyte OLTP database.
